Abstract

The invention provides an implementation method for a reconfigurable aircraft control system. The system comprises a controller module, a torque control and distribution module, a rudder face reconfiguration distributor, a vector thrust reconfiguration controller, two fault recognition units and a state measurement unit. The reconfigurable control system is designed through a weighted generalized inverse method; when an execution mechanism fails, the rapid configurability of the control system can be achieved by only changing the weighted value of a control efficiency weighting matrix without changing the control law; by introducing an indirect control amount, the reversing of the control matrix is not related to the state of the execution mechanism, offline calculation can be achieved, and the calculation amount of a controller is reduced.

Description

technical field [0001] The invention relates to a technology in the field of aircraft control, in particular to a method for realizing a reconfigurable control system of an aircraft with multiple propellers and multiple rudder surfaces. Background technique [0002] There are two ways to reconfigure the aircraft control system in the prior art: one is realized by using hardware (multi-sensor and multi-actuator backup), this method has been applied in the current aircraft control system, but this method brings to increase weight and cost; the other is achieved through a certain fault-tolerant algorithm, which is to make full use of fault information to model the system under fault, and use the redundancy of aircraft aerodynamics and structure to control the method or control according to a certain algorithm. This method is easy to implement and does not increase the cost of hardware, so it is widely used. [0003] After searching the prior art, the Chinese document patent nu...
